RECORDING APPARATUS
BACKGRO~ND OF THE INVENTION
Field of the Invention:
The present invention relates to a recording
apparatus such as a video tape recorder capable of
programming a recording scheduIe using a VCR+ code
(Video+ code).
Description of the Related Art:
There has been proposed a video tape recorder
(VTR) capable of programming a recording schedule using a
VCR+ code. The proposed VTR operates as follows: When
the VTR receives a VCR+ code, it decodes the VCR+ code to
obtain a date/time at which a broadcast program starts, a
time at which the broadcast program ends, and a VCR+
guide channel (second broadcasting station code), and
thereafter writes the date/time at which the broadcast
program starts, the time at which the broadcast program
ends, and a VTR channel or position number corresponding
to the VCR+ guide channel.
To convert the VCR+ guide channel into a
corresponding VTR channel or position number, the VTR has
a memory means for storing data representing the
2097S77
relationship between VCR+ guide channels and VTR channel
or position numbers.
~ As described above, the memory means is
required to store data representing the relationship
between VCR+ guide channels and VTR channel or position
numbers. As shown in FIG. 11 of the accompanying
drawings, a menu indicating such data is displayed on the
screen of a monitor television set 100 by a VTR 50.
While viewing the displayed menu, the user operates on
keys of a remote oontrol commander (transmitter) 60 or
the VTR 50 itself to enter a channel number corresponding
to a desired VCR+ guide channel. However, such a
practice has been very cumbersome.

a tuner control signal such as a station selection
voltage from a VTR microprocessor 3. The tuner 2
supplies the VTR microprocessor 3 with a data signal such
as an AFT signal.
The tuner 2 supplies an output video signal SV
to a video recording circuit 5 and a broadcasting station
code detector 4. The video recording circuit 5 is
controlled in its operation by the VTR microprocessor 3.
The broadcasting station code detector 4 extracts VPS
data inserted in the 16tX H of the vertical synchroni~ing

The recording apparatus also includes memories
6, 7. The memory 6 stores, in advance, data representing
the corresponding relationship between broadcasting
station codes that can be detected from the vertical
: synchronizing interval of the video signal SV and VCR+
guide channels. For example, the data representing the
corresponding relationship between broadcasting station
codes and VCR+ guide channels may be stored in the memory
6 when the recording apparatus is shipped from the
factory. The memory 7 stores data representing the
corresponding relationship between channels that can be
selected by the tuner 2 and VCR+ guide channels upon
automatic setting, as described later on.

: to the VTR microprocessor 3 for detecting an infrared
remote control signal emitted from a remote control
commander 9. The detected remote control signal is
supplied from the infrared radiation detector 8 to the
V~R microprocessor 3. To the VTR microprocessor 3, there

A recording schedule program memory 11
connected to the VTR microprocessor 3 stores programming
information including a date/time at which a broadcast
program starts, a time at which the broadcast program
ends, and a channel when a recording schedule is
programmed.
The VTR microprocessor 3 controls an on-screen
display circuit 12 to control the display of information
on a monitor television set 13.
When the user presses an automatic VCR+ guide
channel setting key on the key input circuit 10 or an
automatic VCR+ guide channel setting key on the remote
control commander 9, a process of automatically setting a
VCR+ guide channel is carried out. Alternatively, the
user can execute a process of automatically setting a
VCR+ guide channel by moving a displayed cursor to
"AUTOMATIC VCR+ GUIDE CHANNEL SETTING" in a menu
displayed on the screen of the monitor television set 13,
with a key on the key input circuit 10 or the remote
control commander 9, as shown in FIG. 2, and then
pressing an execute key.
The process of automatically setting a VCR+
guide channel is carried out according to the flowchart
of FIG. 3.

First, the VTR microprocessor 3 controls the
tuner 2 to select a channel of a smallest channel number
that the tuner 2 can select in a step 20. Then, control
goes to a step 21.
In the step 21, the VTR microprocessor 3
determines whether there is a broadcast signal in the
selected channel based on a data signal from the tuner 2.
If there is a broadcast signal, then the VTR
microprocessor 3 checks a broadcasting station code in
the video signal SV based on a detected output signal
from the broadcasting station code detector 4 in a step
22, after which control goes proceeds a step 23.
- In the step 23, the VTR microprocessor 3
determines whether there has been a broadcasting station
code. If there has been a broadcasting station code,
then the VTR microprocessor 3 reads a guide channel
corresponding to the detected broadcasting`station code
out of the memory 6 based on the data, stored in the
memory 6, which represents the corresponding relationship
between broadcasting station codes and VCR+ guide
~.
channels. Then, the VTR microprocessor 3 writes the
; guide channel in the memory 7 in relation to the channel
that is being selected in a step 24. Thereafter, control
goes to a step 25.

If there has been no broadcasting station code,
then the VTR microprocessor 3 writes data representing
"GUIDE CHA~NEL NOT SET" in the memory 7 in relation to
the channel that is being selected in a step 26.
Thereafter, control goes to the step 25.
If there is no broadcast signal in the step 21,
then the VTR microprocessor 3 writes data representing
"NO BROADCAST" in the memory 7 in relation to the channel
that is being selected in a step 27. Thereafter, control
goes to the step 25.
In the step 25, the VTR microprocessor 3
determines whether all channels have been selected. If
all channels have not been selected, then the VTR
microprocessor 3 controls the tuner 2 to select a channel
whose channel number is incremented by "1" in a step 28.
Thereafter, control returns to the step 21.
If all channels have been selected in the step
25, then control proceeds to a step 29 in which the VTR
microprocessor 3 displays channels for which guide
channels are not set, one by one on the monitor
television set 13, and prompts the user to enter guide
channels using the key input circuit 10 or the remote
control commander 9. Thereafter, the automatic setting
process is ended.

In the above automatic setting process, the
memory 7 thus stores data representing the corresponding
relationship between channels selectable by the tuner 2
and VCR+ guide channels.
A recording schedule is programmed using a
VCR+ code as follows: When a VCR+ code for a broadcast
program whose recording schedule is to be programmed is
entered by the key input circuit 10 or the remote control
commander 9, the VTR microprocessor 3 decodes the VCR+
code to obtain a date/time at which the broadcast program
:starts, a time at which the broadcast program ends, and a
YCR+ guide channel, and thereafter writes the date/time
- at which the broadcast program starts, the time at which
. the broadcast program ends, and a VTR channel or position
number corresponding to the VCR+ guide channel in the
:`recording schedule program memory 11. To convert the
VCR+ guide channel into a channel selectable by the tuner
2, the VTR microprocessor 3 refers to the data
representing the corresponding relationship between
channels selectable by the tuner 2 and VCR+ guide
channels.
;Since the data representing the corresponding
;~relationship between channels selectable by the tuner 2
and VCR+ guide channels are automatically stored in the

memory 7, the user is not required to take the trouble of
setting such data.
In the embodiment shown in FIG. 1, the channel
number varies successively from the minimum value to the
maximum value in the automatic setting process. However,
the channel number may vary in any sequence insofar as
all channels are eventually selected. The user may enter
channels, for which guide channels are to be set, one by
one using the remote control commander 9 or the key input
circuit 10. The remote control commander g emits an
infrared signal to the VTR in the illustrated embodiment.
However, the remote control commander 9 may emit an
ultrasonic signal, an RF signal, or the like, or may
transmit an electric signal if it is a wired remote
control commander.
A recording apparatus according to another
embodiment will be described below with reference to
FIGS. 6 and 7. Those parts shown in FIGS. 6 and 7 which
are identical to those shown in FIG. 1 are denoted by
identical reference numerals, and will not be described
in detail below.

As shown in FIG. 6, an infrared radiation

When the user presses an automatic VCR+ guide
channel setting key on the key input circuit 9b of the
- remote control commander 9, a process of automatically
setting a VCR+ guide channel is carried out.
FIGS. 8 and 9 illustrate a sequence for
automatically setting VCR+ guide channels on the remote
control commander with the recording apparatus shown in
FIG. 6.
First, the microprocessor 9a determines whether
the automatic VCR+ guide channel setting key on the key
input circuit 9b of the remote control commander 9 is
pressed or not in a step 30. If not, then control
~ proceeds to a step 4~.
; If the automatic VCR+ guide channel setting key
is pressed in the step 30, data indicative of a minimum
channel number of channels that are selectable by the
tuner 2 is transmitted from the infrared radiation
emitter 9d to the VTR in a step 31.
. Then, the microprocessor 9a determines whether
data is transmitted from the VTR through the 1nfrared
radiation detector 9e or not in a step 32. If not, then
the microprocessor 9a determines whether a certain period
~ of time has elapsed or not in a step 33. If not elapsed,
:: then control returns to the step 32.

If elapsed, then the microprocessor 9a displays
data "NO VTR RESPONSE" on the display unit 9c, and
interrupts the automatic setting process in a step 34,
after which control goes to the step 45.
If data is transmitted from the VTR in the step
32, then the microprocessor 9a determines whether the
data represents "STATION NOT SELECTABLE" or not in a step
35. If the data represents "STATION NOT SELECTABLE",
then the microprocessor 9a displays data "STATION NOT
SELECTABLE" on the display unit 9c, and interrupts the
automatic setting process in a step 36, after which
control goes to the step 45.
If the data does not represent "STATION NOT
SELECTABLE" in the step 35, then the microprocessor 9a
determines whether the data is a broadcasting station
code or not in a step 37. If the data is a broadcasting
station code, then the microprocessor 9a reads a guide
channel corresponding to the detected broadcasting
.
-~ station code out of the memory 6 based on the data,
~ stored in the memory 6, which represents the
. ~ .
corresponding relationsh1p between broadcasting station
. codes and VCR+ guide channels. Then, the microprocessor
9a writes the guide channel in the memory 7 in relation

to the channel that is being selected in a step 38.
Thereafter, control goes to a step 42.
If the data is not a broadcasting station code
in the step 37, then the microprocessor 9a determines
whether the data is representative of "NO BROADCAST" or
not in a step 39. If the data represents "NO BROADCAST",
then the microprocessor 9a writes data representing "NO
BROADCAST" in the memory 7 in relation to the channel
that is being selected in a step 40. Thereafter, control
goes to the step 42. If the data does not represent "NO
BROADCAST", then the microprocessor 9a writes data
representing "NO BROADCASTING STATION CODE" in the memory
7 in relation to the channel that is being selected in a
step 41. Thereafter, contIol goes to the step 42.
In the step 42, the microprocessor 9a
determines whether the channel numbers of all channels
have been transmitted to the VTR or not. If the channel
numbers of all channels have not been transmitted, then
the microprocessor 9a transmits a channel number
incremented by "1" through the infrared radiation emitter
9d to the VTR in a step 43, and control returns to the
step 32.
If the channel numbers of all channels have
been transmitted in the step 42, then control proceeds to

a step 44 in which the microprocessor 9a displays
: channels for which there are no broadcasting station
codes, one by one on the display unit 9c, and prompts the
user to enter guide channel~ using the key input circuit
9b. Thereafter, the automatic setting process is ended,
and control goes to a step 45.
In the step 45, the processor 9a carries out
other processes of the remote control commander 9. Then,
control goes back to the step 30.
FIG. 10 shows the manner in which the VTR
operates in a process of automatically setting VCR+ guide
channels.
First, the VTR microprocessor 3 determines
.. . whether a channel number is received from the remote
; control commander 9 through the infrared radiation
detector 8 in a step 71. If not received, control goes
to a step 81.
. If rèceived, then the VTR microprocessor 3

- or not in a step 72. If not, the VTR microprocessor 3
transmits data representing "CHANNEL NOT SELECTABLE"
through the infrared radiation:emitter 14 to the remote
control commander 9 in a step 74. Thereafter, control

I~ a channel is selectable in the step 72, then
the VTR miaroprocessor 3 controls the tuner 2 to select a
channel whose channel number has been transmitted from
the remote control commander 9 in a step 73, which is
followed by a step 75.
In the step 75, the VTR microprocessor 3
determines whether there is a broadcast signal in the
selected channel based on a data signal from the tuner 2.
If there is no broadcast signal, then the VTR
microprocessor 3 transmits data representing "NO
BROADCAST" through the infrared radiation emittèr 14 to
the remote control commander 9 in a step 77. Thereafter,
control goes to the step 81. If there is a broadcast
signal, then the VTR microprocessor 3 checks a
broadcasting station code in the video signal SV based on
a detected output signal from the broadcasting station
code detector 4 in a step 76, after which control goes
proceeds a step 78.
~ In the step 78, the VTR microprocessor 3
determines whether there has been a broadcasting station
code. If there has been a broadcasting station code,
then the VTR microprocessor 3 transmits the broadcasting
station code through the infrared radiation emitter 14 to

the remote control commander 9 in a step 79. Then
control goes to the step 81.
If there has been no broadcasting station code
in the step 78, then the VTR microprocessor 3 transmits
data indicating "NO BROADCASTING STATION CODE" through
the infrared radiation emitter 14 to the remote control
commander 9 in a step 80. Then control goes to the step
81.
In the step 81, the VTR microprocessor 3
carries out other processes of the VTR. Then, control
goes back to the step 71.
In the above operation, the memory 7 of the
remote control commander 9 thus stores data representing
the corresponding relationship between channels
selectable by the tuner 2 and VCR+ guide channels.
According to this embodiment, a recording
schedule is programmed using a VCR+ code as follows:
When a VCR+ code for a broadcast program whose recording
schedule is to be programmed is entered by the remote
control commander 9, the microprocessor 9a decodes the
VCR+ code to obtain a date/time at which the broadcast
program starts, a time at which the broadcast program
ends, and a VCR+ guide channel. Then, the microprocessor
9a converts thé VCR+ guide channel into a channel
:,
` 2~97577
selectable by the tuner 2 by referring to the data, which
is stored in the memory 7, representing the corresponding
relationship between channels selectable by the tuner 2
and VCR+ guide channels. Then, the microprocessor 9a
transmits data representing the date/time at which the
broadcast program starts, the time at which the broadcast
program ends, and the VCR+ guide channel through the
infrared radiation emitter 9d to the VTR. The VTR
microprocessor 3 then writes the transmitted data in the
recording schedule program memory 11.
When a VCR+ code for a broadcast program whose
recording schedule is to be programmed is entered by the
key input circuit 10, the VTR microprocessor 3 decodes
the VCR+ code to obtain a date/time at which the
broadcast program starts, a time at which the broadcast
program ends, and a VCR+ guide channel. Then, the VTR
microprocessor 3 transmits the data of the VCR+ guide
.
channel through the infrared radiation emitter I4 to the
. .
remote control commander 9. The microprocessor 9a of the
remote control commander 9 converts the VCR+ guide
channel into a channel selectable by the tuner 2 by
referring to the data, which is stored in the memory 7,
representing the corresponding relationship between
channels selectable by the tuner 2 and VCR+ guide

channels. Then, the microprocessor 9a transmits channel
data through the infrared radiation emitter 9d to the
VTR. The VTR microprocessor 3 then writes the data,
representin~ the date/time at which the broadcast program
starts, the time at which the broadcast program ends, and
the VCR+ guide channel, in the recording schedule program
memory 11.
Since the data representing the corresponding
relationship between channels selectable by the tuner 2
and VCR+ guide channels are automatically stored in the
memory 7 of the remote control commander 9, the user does
not have to set such data.
In the embodiment shown in FIGS. 6 and 7, the
channel number varies successively from the minimum value
to the maximum value and is transmitted to the VTR by the
microprocessor 9a of the remote control commander 9 in
the automatic setting process. However, the channel
number may vary in any sequence insofar as all channels
are eventually selected. The user may enter channels,
for which guide channels are to be set, one by one using
the key input circuit 9b of the remote control commander
9. The remote control commander 9 employs infrared
radiation signals for bidireational communications
between the remote aon~rol commander 9 and the V~R.

; However, such bidirectional communications may be carried
out using an ultrasonic signal, an RF signal, or the
like, or using an electric signal if it is a wired remote
control commander. A wired remote control commander may
be used only in the automatic setting process.
The VTR microprocessor 3 controls the tuner 2
to select a channel whose channel number has been
transmitted from the remote control commander 9, and the
broadcasting station code detector 4 detects a
broadcasting station code. However, as shown in FIG. 6,
with the VTR having the memory 15 for storing data
representing the corresponding relationship between
channels that can be selected by the tuner 2 and
broadcasting station codes, a channel may not be selected
by the tuner 2, and a broadcasting station code may be
determined and transmitted to the remote control
` commander 9.
The remote control commander 9 transmits
~ channel numbers, one by one, to the VTR. However, the
` remote control command 9 may transmit all channel numbers
at once, and may receive result data indicative of
; whether there is 8 broadcasting station code or not from
the VTR .

In the above embodiments, broadcasting station
codes are detected from VPS data inserted in a vertical
synchronizing interval of a television broadcast signal.
However, EDS data in the United States, or PDC data in
England, or character-multiplexed broadcast data may be
detected and used to detect broadcasting station codes.
With the present invention, broadcasting
station codes detected by the broadcasting code detecting
means and the corresponding relationship, stored in the
memory means, between VCR+ guide channels and
broadcasting station codes are used for the processing
means to automatically set the corresponding relationship
between channels selectable by the tuner and VCR+ guide
channels. Thus, it is not necessary for the user to take
the trouble of setting the corresponding relationship.
Although certain preferred embodiments of the
present invention have been shown and described in
detail, it should be understood that various changes and
modifications may be made therein without departing from
the scope of the appended claims.
